Abstract
Abstract A general function for the susceptibility response of disordered systems was recently proposed. It is here shown to be suitable for describing the response of geometrically confined systems. We investigate its ability to describe experimental permittivity data from dielectric spectroscopy and compare its performance with other commonly used curve-fit functions. As a model system we choose to study a propylene carbonate-poly(methyl methacrylate) gel. The physical interpretations of the obtained curve-fit parameters are briefly discussed.
